Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a printer paper feeding mechanism and a printer. Background Art

[0002] The function of a color printer is to output color documents and images, providing vivid and accurate color reproduction. Color printers are often used to print photos, marketing materials, charts, and artwork, and are suitable for occasions that require high-quality visual effects. Color printers can reproduce rich colors and details, making documents and images more vivid and eye-catching. This is especially important in advertising, marketing, and design. Color charts, graphs, and data visualizations are easier to understand and analyze than black and white images.

[0003] Color printers generally spray small drops of ink onto paper through nozzles, mixing different colored inks to generate color images. Common ink colors for color printers include cyan, magenta, yellow, and black. During daily use, printers are prone to paper jams due to improper paper placement or other reasons such as paper being too thick or too thin. When a paper jam occurs in the printer's paper output slot, staff generally manually pull out the jammed paper. Since the printer's paper output slot has a certain depth, it is not easy for staff to easily remove the paper. Therefore, we propose a printer paper removal mechanism and a printer.
